GRAB-HOOK.

SPECIFICATION forming part of Letters Patent No. 631,697, dated August 22, 1.899. Application i'lled February 24, 1899. `Serial No. 706,757. (No model.)

To all whom, it may concern: Be it known that L'LUDGER CHAREST, a citi zen of the United States, residing at Stanley, in the county of Chippewa and State of Wisconsin, have invented a new and useful Grab- Hook, of which the following is a specification.

My invention relates to grab-hooks for connecting chains, and is principally designed for use in connection with chains employed in binding logs to sleds and logging-cars.

The object of the invention is to provide an improved construction of grab-hook whereby I secure important advantages with respect to efficiency in use.

The invention consists in the novel construction and Vcombination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a grab-hook constructed in accordance with my invention, the same being shown closed in full linesl and opened in broken or dotted lines. Fig. 2Yis a central longitudinal section. Fig. 3 is an elevation of the locking-lever.

In the said drawings the reference-numeral 1 designates a metal block formed with a slot 2 at one end and with lugs or extensions 3. Near the other end said block is formed with a hole 4.-, with which one end of the chain (not shown) is permanently secured. The numeral 5 designates a cross-piece formed integral with said block and forming a stop for the hooked lever 6. This lever is pivotedto the said lugs or extensions and consists of an arm 7 having a curved recess 8 at the free end and at the other end formed with a hook 9 with a space 10 therebetween to receive the link of the chain, as will be well understood by those familiar with the art to which the invention pertains. Secured to said arm is' a spring 12, the tension of which can be regulated by a set-screw 13. The upper end of this spring engages a recess 14 in said block. The numeral 16 designates a cold-shut clevis lelogram, with the short portions thereof passing through holes 16 and 17 in a locking-lever 18 and said block, respectively. This lock-V in g-lever is fulcrumed on one of the said short arms of the clevis and is formed with a cam 19, which is adapted to engage the recess S of the hooked lever.

The operationwill be readily understood. I

One end of the chain is secured to the hole in the block 1, while the other end is passed around the load to be bound, and one of the links of the chain is engaged between the arm 7 and the hook 10. The lever-arm is thrown inwardly and the locking-lever forced down, so that the parts will occupy the-positions shown Ain Fig. 2. The spring will prevent wabbling of the parts and will also lock the locking-lever and prevent the cam thereof from being thrown out of engagement with the recess 8 of the hooked lever. To disengage the oh ain,the locking-lever will bethrown upwardly into the position shown by the dotted lines at the upper part of Fig. 1, when the tension of the chain will pull the hooked lever downwardly in the position shown by the dotted lines at the lower part of said iigure. The chain will now slide off the hooked lever.

Having thus fully described m'y invention, what I claim is- In a grab-hook, the combination with the slotted block, the hooked lever pivotally connected therewith formed with a curved recess and the spring secured to said lever, of the clevis connected with said block and the lock-A LUDGER CIIAREST.
